Abstract: 3824. Bylger, F. I. L. Feb. 14. Disk-engine and inclined-shaft type; packing drums, vanes, etc.; adjusting parts for wear.- A disk engine comprises a shaft 2, Figs. 1 and 2, carrying a hollow trunk 4, upon which are mounted two disks 5, each of which co-operates with an inclined disk 6. The disks 6 are provided with conical faces 7 which contact at the line 8, the conical faces being supported at other points by conical roller bearings 9. Peripheral roller bearings are also provided to take the weight of the disks 6. Each of the disks 5 has a spherical hub 10 and inner and outer spherical shells 14, 11. Supported by webs on each of the disks 6 are rings 15, 16, the ring 15 fitting between the hub 10 and shell 14, and the ring 16 fitting between the shells 11, 14. The faces of the rings 15, 16 and the disk 5 are conical and roll in contact, the line of contact being stationary. The shell 14 divides the enclosed space into two concentric working chambers. Each chamber contains two vanes 31 or 32, Figs. 1, 2, and 3, which are rigidly secured to the disk 5 and have a sliding-rocking connexion with the inclined disk 6. Each vane slides into a pocket 34, Figs. 1 and 4, carried by the disk 6, a cylindrical packing-piece 36, Fig. 4, allowing the vane to rock relatively to the pocket. In addition, the pocket itself is capable of slight rotary movement about a pivot 42. The combined motion thus obtained permits the two elements of each rotor to work in true rolling contact. Packing-devices for preventing steam from leaking into the pockets 34 are described in detail. Steam is supplied to the engine through a conduit 29 to the space between the shaft 2 and the trunk 4, whence it passes into radial steam-chests 28, Figs. 1 and 9, in which oscillating valves 27 are situated. Each of the chests 28 is provided with a port communicating with a working chamber and an exhaust port 30 leading to the interior of the outer casing 1. The valves 28 are operated through suitable link-work by one of two sets of pawls, according to the direction of rotation required, working in connexion with two sets of stationary cams 78, Fig. 2. A clutch 94, operated from a shaft 100. renders one set of pawls inoperative by disconnecting them from the axial valve-actuating shafts. These shafts are shown in dotted lines in Fig. 2 and are situated in the space between the shaft 2 and the trunk 4. Wear is compensated for by the following device. The left-hand disk 5 is mounted rigidly upon the trunk 4. The disks 6, being idlers, are capable of axial movement. The right-hand disk 5 cannot revolve on the trunk 4 but can slide axially thereon. A steampressure chamber 113, Fig. 2, allows the steam to press the disk 5 to the left, whereupon any wear of the rolling parts is taken up. The steam may be used expansively and the amount of cut-off varied by providing for the rotation of the cams 78. The inner and outer working chambers are provided to allow compound working. The invention is applicable to pumps and compressors.
